At the beginning of the reaction, the copper particles with high surface activity made the reaction violently, and then the reaction rate dropped rapidly due to the oxidation of a large number of copper particles by hydrogen peroxide.
At the beginning of the reaction, highly surfactable copper particles cause the reaction to take place violently, and then the reaction rate decreases rapidly due to the oxidation of a large number of copper particles by hydrogen peroxide.
